Method of installing poles in a rock surface

ABSTRACT

A method for installing poles in rock surface which includes the step of firstly drilling an annular hole in a rock. The annular hole being drilled such that a centrally positioned core of rock remains extending upwardly through the annular hole. Next, a pole is provided that has a first end and a second end; with a socket positioned at the first end. Finally, the first end of the pole is positioned within the annular hole such the central core of rock is received in the socket at the first end of the pole to provide additional stability to the pole.

FIELD OF THE INVENTION

The present invention relates to a method of installing poles in a rocksurface

BACKGROUND OF TBE INVENTION

There are known methods of installing poles in rock surface. One methodinvolves the use of anchors bolts which are drilled into the rocksurface. The anchor bolts are then used support a utility pole in anupright position on top of the rock surface. This method is expensive asanchor bolts are required for each utility pole erected. Furthermore,this method is also time consuming as several holes are required to bedrilled into a rock surface in a specific relation to each other inorder to accommodate the anchor bolts. Finally, if one of the anchorbolts becomes loose in the rock bed, or becomes damaged, then theutility pole may become unstable and topple over.

Another method of installing utility poles into a rock surface or bedinvolves drilling a hole to a desired depth and positioning the uprightutility pole in the hole. After the utility pole has been positioned,cement is then placed in the hole to add to the pole's stability.

SUMMARY OF THE INVENTION

What is required is an easier, less costly method of installing poles ina rock surface.

According to the present invention, there is provided a method forinstalling poles in rock surface which includes drilling an annular holein the rock surface. The annular hole is drilled so that a centrallypositioned core of rock remains extending upwardly in the annular hole.A pole is provided having a first end and a second end. A socket ispositioned at the first end. The first end of the pole is thenpositioned within the annular hole such the central core of rock isreceived in the socket at the first end of the pole.

Although beneficial results may be obtained through the use of themethod, as described above, even more beneficial results may be obtainedwhen the first end of the pole is a drilling bit used to drill theannular hole in the rock surface.

According to another aspect of the present invention there is provided apole which includes an elongate body having a first end and a secondend. The first end has an annular edge defining a socket. The annularedge has teeth, such that the first end is adapted to serve as a drillbit for the purpose of drilling an annular hole to accommodate the body.

It will be appreciated that the pole described above, may be made with atubular body.

BRIEF DESCRIPTION OF THE DRAWINGS

These and other features of the invention will become more apparent fromthe following description in which reference is made to the appendeddrawings, the drawings are for the purpose of illustration only and arenot intended to in any way limit the scope of the invention to theparticular embodiment or embodiments shown, wherein:

FIG. 1 is a top plan view of an annular hole drilled in accordance withthe preferred a method of installing poles in a rock surface.

FIG. 2 is a side elevation view, in section, of the annular hole,illustrated in FIG. 1, being drilled with a core drilling bit.

FIG. 3 is a side elevation view, in section, of a utility polepositioned in the annular hole.

FIG. 4 is a side elevation view, in section, of a utility pole having adrilling end for drilling the annular hole.

DETAILED DESCRIPTION OF TIIE PREFERRED EMBODIMENT

The preferred method of installing poles in a rock surface will now bedescribed with reference to FIGS. 1 through 4.

Referring to FIG. 1, the preferred method for installing utility polesin a rock surface involves first drilling an annular hole 10 in a rocksurface 12. Annular hole 10 is drilled so that a centrally positionedcore 14 of rock remains extending upwardly through annular hole 10.Referring to FIG. 3, a utility pole 16 is provided that has a first end18 and a second end 20. First end 18 of utility pole 16 has a socket 22.

In order to install utility pole 16 in rock surface 12, first end 18 ofutility pole 16 is then positioned within annular hole 10 such centralcore 14 of rock is received in socket 22 at first end 18 of utility pole16. The central core 14 of rock positioned within socket 22 providesadditional stability to utility pole 16. Not only does the abovedescribed method provide greater stability, it actually takes less timeand is, therefore, less costly to drill an annular hole.

Referring to FIG. 2, a core drilling bit 24 can be used to drill annularhole 10 to a desired depth. The size of the diameter of core drillingbit 24 is selected so that annular hole 10 that is drilled has an outerdiameter slightly larger than an outer diameter of utility pole 16, andcentrally positioned core 14 has a outer diameter slightly smaller thaninner diameter of socket 22 of utility pole 16 as illustrated in FIG. 3.This ensures that there is a good fit between utility pole 16 andannular hole 10.

It will be appreciated that although the preferred method has beendescribed for use with utility poles, the method described above canalso be used to install other types of posts or poles so long has theyhave a hollow body or socket at one end that is adapted to receivecentrally positioned core 14 in annular hole 10.

Referring to FIG. 4, as an alternative to the use of core drilling bit24 illustrated in FIG. 2, socket 22 of utility pole 16 can be providewith a drilling edge 26 with teeth suitable for drilling through rocksurface 12. Utility pole 16 itself can then be rotated to drill annularhole 10 of a suitable dimension. Centrally positioned core 14 is stillreceived in socket 22 of utility pole 16. This innovation allows theinstallation of the pole to be a “one step” procedure, instead to firstdrilling the annular hole and then installing the pole.

In this patent document, the word “comprising” is used in itsnon-limiting sense to mean that items following the word are included,but items not specifically mentioned are not excluded. A reference to anelement by the indefinite article “a” does not exclude the possibilitythat more than one of the element is present, unless the context clearlyrequires that there be one and only one of the elements.

It will be apparent to one skilled in the art that modifications may bemade to the illustrated embodiment without departing from the spirit andscope of the invention as hereinafter defined in the Claims.
